Possible to force my java app to use more CPU utilization?

If it has millions of frames, it is. That was just an example where Java is terrible. It comes up frequently when dealing with files that weren't created by Java. Can come up dealing with databases too.

A GIF with millions of frames, huh? If this was a video at 60fps, that would be 277 minutes worth of GIF. It also would be one huge file.

I read files that weren't created by Java all the time, however I can deal with the twos compliment bytes. In fact, most of the time I don't need to work with the byte directly but, when I do, I can deal with the twos complimented numbers Java displays.

I don't why this thread turned into an argument about Java. Java was probably one of the first languages designed for corporations by corporations and it shows , that's all there is to it. Not a whole lot of new software is built with Java from the ground up nowadays , sure there is a lot of maintenance to be done on the mountains of software that have been written in the early 2000s so it's usage somewhat skews the reality of things.

Java would literally by my last choice for 2D graphics or any kind of graphics , OP chose the wrong tool for the job , nothing will properly mend that or be worth the effort and hassle.

I would argue that Node.js, Ruby, or PHP are less adequate than Java for rendered graphics but, I'm not disagreeing. Java wouldn't be my go-to for visualizations either, but that isn't to say it can't do it though and choosing to use the right tools inside the ecosystem helps as well. Fighting against a platform doesn't tend to help give you traction and Swing is probably the last thing you want to use.

Thing is Java falls into that grey area of languages that look like can be used for anything unlike those, who are widely recognized as being suitable for a specific set of tasks.

I know a lot of people who would argue that Node can be used for everything. People have opinions about these things but, at the end of the day, they're all Turing complete languages, each with their own strengths and weaknesses. I mean, at the end of the day if the only thing you care about is performance, you might as well just write it in C and call it a day. Java is very mature, it has a lot of well maintained libraries, and it runs everywhere. Those are things that are valuable to developers. I don't tend to write Java anymore, I usually write Clojure which, at the end of the day, compiles to Java byte code and runs on the JVM. It works for what I typically need and it gives me the ability to tap into any of the Java or Clojure libraries that have been written and put into Clojars or Maven Central.

For example, Google's cloud api library for Java is incredibly well maintained and the devs are very quick to address issues. If you're using something like GCP, that's worth its weight in gold to a business.

I almost gave you thumbs up, but you had to say Clojure
I'm more of a Scala guy

What if you had to do cross-platform graphics?
At the end of the day, it gets the job done. Ask Minecraft
Plus, in the age of microservices, you can take advantage of Java's TTM and rewrite later if you need to squeeze more out of it. I mean, the OP seems to be doing just some prototyping atm.

All i like about Java is that when I detect it, I reformat. (just kidding, but when I detect it, I go into hunter mode: What fucking application did bring this shit?))

It's probably not the best thing to have on your home PC, but it's on virtually every server out there. It powers useful stuff as Apache Kafka or Spark.

Ehhh. I've had enough of OO and the havoc it can wreak. Clojure(Script,) has the added benefit of being able to compile to JavaScript too which is nice for the browser (I personally really like Reagent.)

It's a big reason why I suggested LWJGL if the OP is sticking with Java and Minecraft actually can run really well despite being on Java.

Good enough for large scale applications running on servers, but not okay for workstations? Interesting.

It really doesn't. It runs a lot better on the other platforms it has been ported to. Even the UWP version.

Yeah, functional solves many problems more elegantly. It's just that lisp syntax has never jived well with me, that's all.

Java's problem is not that it doesn't run well. In some benches it can match C for speed. Its problem is it needs a lot more memory than other solutions and it sometimes takes a while for JIT to kick in.

Workstations wouldn't have a problem (other than having to juggle JREs), that's why I said home PC.

I took a course in Java when I was in college. It was a great language to learn the concepts of OOP. Most of what I'm doing is for proof of concept, and not so much for professional consultation purposes. There's plenty of resources available on the Web to answer just about any question you have about Java. Java is also similar in syntax to other high level languages and I think that's a bonus. I'm now dabbling in C# as per a recommendation on a prior post. I'm finding the syntax very similar to Java.

P.S. I'm no longer receiving email notifications for new posts in this thread...

C# exists because Sun sued Microsoft over using JVM in J++ (Microsoft adaptation of Java). Microsoft went on to create the .NET Framework and J# (literally Java on .NET) and C# (C++ on .NET). If you can hunt down a version of Visual Studio 2005, that was the last to have J#. C# was so popular that they decided to axe support for J#.

I remember J++ and I haven't used it in ages. Interesting how things turned out.
